EXTERNALLY ADJUSTABLE VENTURI. FIGURES 12A - 12C.
An externally adjustable venturi has been incorporated into the millivolt board assembly for this fireplace. Follow the instructions
below for proper operation and settings.
CAUTION: THE SURFACES OF THIS FIREPLACE ARE HOT WHILE THE BURNER IS IN OPERATION. ALLOW THE FIREPLACE TO
COOL PRIOR TO ADJUSTING THE VENTURI OR USE EXTREME CAUTION AND WEAR THE APPROPRIATE
PROTECTION TO AVOID SERIOUS BURNS.
Referring to the millivolt board above, locate the adjustable venturi lever attached to
the bottom of the millivolt board.
1. The venturi has been factory set for a typical minimum venting configuration
using Natural Gas.
Natural Gas: Lever is positioned in the left notched out section of the bracket
as shown in Figure 12A. This is approximately 1/4" opened.
LP Gas: Lever is positioned in the right notched out section of the
bracket as shown in Figure 12B. This is approximately 5/8" opened.
Figure 12A
The lever may be adjusted in small increments by pulling the lever down slightly
and sliding it in either direction, placing the slots in the lever(under the millivolt
board) into the smaller notches on either side of the factory-set positions.
ADJUSTMENTS:
Placing the lever to the right will close the venturi air collar allowing less air
to be mixed with the gas in the burner tube.
Placing the lever to the left opens the venturi collar allowing more air to be
mixed with the gas in the burner tube. Figure 12B
NOTE: Each fireplace installation is different - i.e.: Venting configuration, chimney system used, etc. Adjust the venturi
opening as necessary to achieve proper burn and appearance.
CAUTION: Do not close the shutter too far! This will cause the fireplace to burn ‘dirty’ which will result in soot
accumulation inside the glass, the firebox and possibly the logs.
